论文摘要
可以将丽莎带中大量黑洞二进制的引力波镜头镜头。当晶状体的schwarzschild半径小于辐射的波长时，镜头信号中的波晶效应至关重要。这些频率依赖性效应可以使我们能够仅使用单个检测来推断透镜参数。在这项工作中，我们通过使用分析溶液对点质量和奇异等温球透镜进行信息 - 摩正质分析来评估通过LISA对波启动效应的可观察性。我们使用重力波形模型，包括合并，响声，更高的谐波和对齐的旋转来研究波形模型和源参数如何影响镜头参数中的测量误差。我们发现，以前的工作低估了波启动效应的可观察性，而丽莎可以检测具有较高影响参数和较低晶状体质量的镜头信号。
The gravitational waves emitted by massive black hole binaries in the LISA band can be lensed. Wave-optics effects in the lensed signal are crucial when the Schwarzschild radius of the lens is smaller than the wavelength of the radiation. These frequency-dependent effects can enable us to infer the lens parameters, possibly with a single detection alone. In this work, we assess the observability of wave-optics effects with LISA by performing an information-matrix analysis using analytical solutions for both point-mass and singular isothermal sphere lenses. We use gravitational-waveform models that include the merger, ringdown, higher harmonics, and aligned spins to study how waveform models and source parameters affect the measurement errors in the lens parameters. We find that previous work underestimated the observability of wave-optics effects and that LISA can detect lensed signals with higher impact parameters and lower lens masses.
